Simulation and Analysis of Pressure Loss and Flow Rate of Fire Engines

Pressure losses have great impact on firefighting operation of fire engines. The pipeline model in AMESim is built according to compressed air foam fire truck AP80; the fluid medium is simulated by setting different fluid parameters; the centrifugal pump is replaced by a constant current source; the length and diameter of the pipeline refer to the actual parameters of AP80; and the pneumatic valve in the pipeline is simulated by a solenoid valve model. Because of the low water pressure, the fluid is considered as incompressible fluid, the pressure of the constant current source is considered as the overall pressure loss of the pipeline as well. By simulating different working conditions, the pressure loss and flow rate under different working conditions are putting forward. It plays an active role in improving the firefighting capability, and is of great significance to the future study of pressure loss about fire engine.
